Former Pompey striker Yakubu has announced his retirement from football.
The Nigeria international joined the Blues on loan from Maccabi Haifa in January 2003.
He scored seven goals in 14 appearances as Harry Redknapp’s troops clinched the Division One title.
Yakubu then made his switch to Fratton Park permanent that summer.
He netted a further 29 goals from 67 appearances before completing a £7.5m move to Middlesbrough in 2005.
On his 35th birthday, Yakubu told Sky Sports News: ‘I would like to officially announce my retirement from professional football today.
‘Firstly, I would like to thank God for the career I have had.
‘I would like to thank the entire Nigerian Football Federation and my Nigerian national team-mates for all the memorable years I had playing for the Super Eagles.
‘I would also like to thank all the football clubs I played for. The managers, all club staff, owners, fellow players and my dearest family and friends who immensely supported me throughout my career.
‘When I started my career at Julius Berger in Nigeria all those years ago (1997) I could only have dreamt of the success that was to follow years after.
‘Also playing in England especially helped me grow as a player and as a person so much that I am now settled here. I feel the time is right for me to now focus on the next chapter in my life.’
Yakubu left Coventry City in April after making just three appearances for the Sky Blues.
